White House press secretary Sarah Sanders on Monday said that is exploring whether to remove the security clearance of former CIA Director and other top Obama-era intelligence officials.

Sanders accused Brennan, former Director of National Intelligence , former FBI Director and others of “politicizing” and “monetizing” their public service.

“They’ve politicized and in some cases monetized their public service and security clearances,” Sanders said during the daily briefing. “Making baseless accusations of improper contact with Russia, or begin influenced by Russia against the president is extremely inappropriate and the fact that people with security clearances are making these baseless charges provides inappropriate legitimacy to accusations with zero evidence.”

Sanders’ comments came after Sen. (R-Ky.) suggested on Twitter that Brennan should have his security clearance revoked.

“Is John Brennan monetizing his security clearance? Is John Brennan making millions of dollars divulging secrets to the mainstream media with his attacks on @realDonaldTrump?” Paul wrote. He said he was meeting Monday to ask Trump to remove Brennan’s security clearance.

Brennan and other former officials have been publicly critical of the president’s comments about Russian interference in the 2016 presidential election.

Trump sparked bipartisan criticism last week when he cast doubt on the intelligence community’s assessment of Russian election interference – a remark he later walked back.

Sanders also said Monday that Trump is “looking to take away” security clearances belonging to former Obama national security adviser Susan Rice and former FBI deputy director – the FBI official who was fired by Attorney General in March before the publication of an inspector general report that criticized his conduct.
